PROBLEM TO BE SOLVED: To provide photochemically cross-linked polysaccharide derivatives that do not contain photopolymerisable functional group prior to the cross-linking, which can be substantially used as a carrier material for chromatographic separation of enantiomers. SOLUTION: In the photochemically cross-linked polysaccharide derivatives, OH groups as OR groups have been esterified or converted into carbamate (urethane) or mixtures thereof, with the proviso that OR groups do not contain polymerisable double bonds prior to the cross-linking.
